I'm placing an order for an X5 and had planned on buying Smartphone Integration. My assumption that this is necessary for the iPHone to play music through the car's audio system. My dealer called me today and told me "it's just a plastic insert and costs $150 so we'd recomend that you not get it." So I deleted it from my order. Now I'm concerned.

I want to 1) connect my iphone to a charger in the car easily, 2) be able to play music from my iPHone through my car's audio easily and 3) don't want a bunch of cords handing around the dash. Is Smartphone Integration the way to go?

BMW's marketing of this feature is horrible.
